Seachem Alkaline Regulator 1kg — High-Capacity Alkaline Buffer & Water Conditioner For Large Tanks Housing African Cichlids, Livebearers, & Other Alkaline-Water Species
Seachem Alkaline Regulator 1kg (SKU: 725043-97) provides high-capacity pH elevation and tap water conditioning for large display aquariums and multi-tank setups. It elevates pH into the 7.1–8.5 range while building carbonate hardness (KH) to buffer against organic acidification. Seachem Alkaline Regulator is designed to raise and stabilise pH in freshwater aquariums, creating ideal conditions for fish species that thrive in alkaline water. It buffers water chemistry to help prevent sudden pH fluctuations that can stress or harm aquatic life.
This 1 kg container also acts as a complete water conditioner, removing chlorine, chloramines, and toxic ammonia during tap water fills. Combined with Seachem Neutral Regulator, it enables precise target pH adjustments across large systems. This product is commonly used in aquariums housing African cichlids, livebearers, and other alkaline-water species. It can be dosed daily until the desired pH level is achieved, allowing controlled and gradual adjustment.
